What kind of cooling would we need to keep a stick at 250mhz? xD

I've got a pretty weak 120mm fan cooling 9 of them, and they are maybe 10 C hotter than room temperature when running 250MHz- and this is in a hot shop, around 35 C.  Probably whatever fan you have is fine for a couple sticks, especially if you're only going to 250.

 
Excellent Smiley  Though I haven't had much trouble getting past 250, the new initialization routines should make it easier to get it above...wherever I left off.

Yeah, well, most people can't build cgminer or modify it themselves, especially on windows.  I've also got a stick to run 425MHz stable/low HW errors, although that just playing with one of the older ones.  It's probable you can beat that if you either get a slightly better chip, better cooling, or one of the v0.5s that you can't explode the chip by going into the "dead zone." (which would help you get a few extra mV).  The new top clock is 500MHz which is the highest I have hex values for.  That's pretty sporty for a USB stick as 425MHz was pulling about 2.5 amps on the USB port.
